Sledgehammer70 also posted in a separate forum detailing the free maps and new mission mode that will release alongside this update. Although the patch notes are pretty short, it has a new map and mode, which is the main point of this update.

Additional Content/Functionality

New Mission: Rebel Depot on Tatooine added as a new Survival Mission.

New Map: Survivors of Endor added to Walker Assault, Supremacy, and Turning Point.

We also expect the first expansion pack for the game to drop sometime this month, although EA have not mentioned any sort of release date, we know it is hitting platforms in March.
